RESP 211 ABG & O2

QuestionAnswer
The oxyhemoglobin dissociation curve depicts the relationship ________________________. Between percentage saturation of oxygen and partial pressure of oxygen in arterial blood.
Calculate a patient's arterial oxygen content if HB=11 gm%, PaO2=90 mmHg, and SaO2=80%. CaO2=(Sat% x HB x 1.34) + (PaO2 x .003), answer 12.2%
Prior to TX, PT ABG were pH 7.37, PaO2 50 mmHg, PaCO2 75 mmHg.The Dr. ordered high flow O2 via non rebreathing mask.Over the next 4 hrs, PT became somewhat confused, lethargic, and breathing is shallow and slow. This is consistent of loss of hypoxic drive
A state of acidemia exists when:A.the HCO3 is >24 mEq/L, B.the blood pH is <7.35, C.the blood pH is 7.45, D.the HCO3 is <24 mEq/L. B. the blood pH is <7.35
Calculate the PAO2 breathing ambient air at an Indian village in the Peruvian Andes, barometric pressure is 400 mmHg. PAO2 = .21(400-47). PAO2 is 74 mmHg.
The following ABG results from a PT who is spontaneously breathing room air: PaO2 55mmHg, PaCO2 58mmHg, pH 7.36, HCO3 32 mEq/L. Describe PT condition. Compensated respiratory acidosis
Which measurement best assess the presence or absence of ventilatory failure? A.PaCO2, B.PaO2, C.pH, or D.HCO3 A. PaCO2
Which of the following would be inconsistent with respiratory alkalosis? A.pH 7.57, B. PaCO2 30mmHg, C. pH 7.63, D. PaCO2 42mmHg D. PaCO2 of 42 mmHg
When the blood PCO2 decreases, the O2 dissociation curve shifts to the ______. A.right & P50 decreases, B.left & P50 increases, C.right & P50 increases, D.left & P50 decreases D.left & P50 decreases
Interpret the following ABG data: pH 7.17, PaCO2 42mmHg, PaO2 100mmHg, and HCO3 16 mmol/L. acute metabolic acidosis
